Hybrid composite cable with an increased specific strength for tensioned structures

Numerical solution of base shear in high tensioned cable antenna

A finite element solution based on equevalent elements is proposed for the static and dynamic analysis of tallhigh tensioned cable antennas. To reduce high number of degrees of freedom in space frame body of a structure, a simple equivalent beam element is defined for each simulative substructure. This numerical procedure is applicable to analyze complex three dimensional assemblies of substruc...

Hybrid carbon fiber composite lattice truss structures

Optimal design of composite structures for strength and stiffness: an inverse homogenization approach

We introduce a rigorously based numerical method for compliance minimization problems in the presence of point wise stress constraints. The method is based on new multiscale quantities that measure the amplification of the local stress due to the microstructure. The design method is illustrated for two different kinds of problems. The first identifies suitably graded distributions of fibers ins...

The development and scalability of a high strength, damage tolerant, hybrid joining scheme for composite-metal structures

Advanced hybrid joints, which incorporate a specially designed array of macro-scale pins that provide mechanical interlocking reinforcement, have been developed in order to address the challenges associated with joining fibre reinforced composites to metals. In the present work, important joint characteristics including strength, mechanical fatigue, damage tolerance and durability have been stu...
